How to apply foliar fertilizer to tea in summer? Please introduce that the temperature in summer is high, drought is common, the root of tea tree is limited by water conditions, the absorptive capacity is weak, and the effect of root fertilization is poor. Foliar fertilizer spraying during the growth period of summer tea can not only increase the yield of tea, but also enhance the tenderness of new buds, which is beneficial to the improvement of the quality of summer tea. The experiment shows that spraying fertilizer on tea leaves can increase the yield of tea by about 10%. The specific method is as follows: urea 0.5-1%, ammonium sulfate 1%, calcium superphosphate 1-2%, potassium sulfate 0.5-1%. The application time is that the new shoots stretch vigorously, the cloudy day when 1 bud and 1-2 leaves unfold, evening or morning is better. Use 5-100 kg fertilizer solution per mu each time and spray it every 3-6 days. When spraying, both sides of the front and back should be sprayed at the same time, especially on the back of the leaves. In the process of spraying, it is necessary to avoid high temperature exposure, cause water evaporation and change fertilizer concentration, and at the same time prevent fertilizer from being leached on rainy days. At the same time of foliar fertilizer spraying, it is still necessary to strengthen the topdressing of tea roots in order to promote each other.
